  • Patent number: 9976922
    Abstract: The disclosure relates to a pressure sensor for measuring a fluid pressure, in particular a vacuum pressure. The pressure sensor contains a first and a second diaphragm connected to one another such that they enclose and hermetically seal a fluid space. Fluid can enter and exit the fluid space through a fluid supply element, which is connected to an exterior opening of the sensor. Each of the diaphragms is proximal to a reference electrode and forms a variable capacitor, the capacitance of which depends on the position of the diaphragms, which in turn depends on the pressure in the fluid space.

  • Publication number: 20170167938
    Abstract: An improved Pirani sensor uses a measuring element disposed within a fluid between a base plate and a cover. The measuring element is held by suspension members that are connected to the base plate. A heating element is thermally conductively connected to the suspension members. Using the sensor the characteristic of the fluid is determined by evaluating the heat transfer from the thermal element through the fluid into the cover when heating power is applied to measuring element. Parasitic conductive heat loss from the measuring element into the suspension members is compensated by applying power to the heating element.

  • Patent number: 8841115
    Abstract: The present disclosure describes use of filamentous algae to form insulating construction materials which provide thermal and noise insulation. Algae from the order Zygnematales, the Cladophorales, or the Ulotrichales can be dried and formed for use as insulating material. Algae mass can be combined into several layers, using a binder to attach the layers to each other. A composite material of algae mass and an additive can be used and form the body of insulation panels having honeycomb-shaped chambers, which are sealed by a foil that is laminated onto the body.

  • Patent number: 8047711
    Abstract: A thermocouple vacuum sensor is provided, the thermocouple being surrounded by a gas or mixture of gases the pressure of which is to be measured. Cyclically the thermocouple is heated until its temperature reaches an upper temperature threshold. The thermocouple is subsequently cooled until its temperature reaches a lower temperature threshold. The heating time required to heat the thermocouple from the lower to the upper temperature threshold is measured. The cooling time required to cool the thermocouple from the upper temperature threshold to the lower temperature threshold may also be measured. The pressure surrounding the thermocouple may then be determined as a function of either the heating time, or the cooling time, or both.

  • Publication number: 20110167919
    Abstract: An interoperable vacuum measuring device is presented, which automatically adjusts to one of two or more vacuum sensors having different electrical characteristics. The interoperable vacuum measuring device in a first step detects which type of vacuum sensor it is connected to. In a second step it controls and evaluates the vacuum sensor, using control parameters determined in response to the detection of the first step. Detection of a vacuum sensor type is achieved by measuring the electrical resistance between any two pins of a vacuum sensor's connector and comparing the measured resistance values with stored resistance values of known vacuum sensors. Further, a vacuum measuring device is presented, which automatically identifies a vacuum sensor, and associates a vacuum pressure measurement with a vacuum sensor. The identification of a vacuum sensor is facilitated by an identification disk, which is placed onto and operatively connected to the male terminals of a vacuum sensor's connector.

  • Patent number: 6722199
    Abstract: A sensor for detecting a rotational movement or an angular acceleration has at least one heating element and at least one sensor element and a fluid surrounding the heating element and the sensor element, the heating element producing in the fluid a convection flow zone through which an isothermal field is defined. The heating element and the sensor element are arranged with respect to an axis of rotation of the rotational movement or of the angular acceleration to be detected, in such a way that the sensor element is displaced relative to the isothermal field when a rotational movement or an angular acceleration takes place.

  • Patent number: 6675656
    Abstract: A force or pressure sensor structure has a membrane and a counter-structure, both being provided with electrodes for determining capacitors. There are at least two capacitors connected in series or in parallel for determining a desired pressure/capacitance dependence or a desired force/capacitance dependence. The counter-structure preferably is fixed and has a multiplicity of electrode areas in the shape of segments of a circle in order to assemble electrode areas obtained by optimization in a series or parallel connection. The interconnection of the individual elementary capacitors are preferably realized by a multilayer construction. The same membrane and an identical evaluation circuit can be used for any pressure/capacitance or force/capacitance dependence desired, with only the multilayer construction requiring modification for a different dependence. The electrode structures can preferably be defined by a few specifications, such as e.g., length, width, spacing or angle, radius, respectively.
